Harvard Catalyst developed the Shared Health Research
Information Network (SHRINE) to support researchers in planning and performing population-based research, such as compiling large groups of well-characterized patients or repeating study results. Qualified investigators can use the SHRINE web-based Query Tool to determine the aggregate total number of patients at participating hospitals who meet a given set of criteria using both inclusion and exclusion logic. Characteristics on which you can query include demographics, diagnoses, medications, and selected laboratory values. Because counts are aggregated, patient privacy is protected.
